INVENTUR BENJAMIN QHANLY, or OAKLAND, CALIFORNIA.

' Application filed May 19,

To all whom it may concern V Be it known that I, BENJAMIN M. HA LY, acitizen of the United States, residing at Oakland, in the conntybtAlameda and State of'California, have invented new and usefulImprovements in Hot-Rivet Passer-s, of which thefollo'wing'is aspecification.

The present invention relates to apparatus for delivering hot rivetsfromv a rivet forge or furnace to variouspoints of a ship, build ing orother construction j oh. I

The primary object of the invention is to provide comparativelyinexpensive and simply constructed and operated apparatus of thecharacter described which will deliver point or points and to ordinarilyinaccessible places, in a more expeditious, reliable and convenientmanner and Without danger of injury to workmen or requiringtheemployment of as many workmen or rivet forgers and other equipment asare necessary under thepresent hand passing system, wherebya saving inlabor, time and expense isprovided. Anotherobject of the invention is topro vide apparatus of the character described which will entirelyeliminate the necessity ofpassing hot rivets by hand and insure thedelivery of each rivetto the predetermined or designated point wherebydropping, cooling otf and loss of rivets are prevented.

The invention possesses other advantages and features some of which,with the toregoing willjbe set forth at length in the followingdescription where I shall outline in full that form of the inventionwhich I have selected for illustration in the drawingsac companying andforming apart of the present specification. In said drawings I haveshown one formof the construction of my 1nvention,-but 1t lstobeunderstood' that I do not limit myselt to such jformslngce theinvention as expressed in theclaims'may be embodied in a plurality of'forms. Referringtothedrawings:

The workmen may shiftthe-bucket to any one ofthe take-oil openings in the take-oft pipe which pipe may be from 15 tofeet or longer, with as many take-off openings as desired. In this waythe'delivering of hot rivets to any part of the hull or building may beprovided for in a reliable, cheap and time savingmannerr One practicalembodiment of the invention is illustrated, in the accompanyingdrawings, in connection with a ship hull, and comprises a system ofpipingl made up of pipe sections having adiameter sufficient to permitrivets to be rapidly impelled there through. These sections extendvertically as -at Qthen horizontally asat 8 and then vertically as at41, which section 4 is the take-oft pipe. Said section may be otherwisearranged as desired Theupper end of the section 2 isarranged adjacent toa rivet forge or furnace '5 which, as shown, is installed upon the deck6 of a ship hull. An inclined intake pipe? is disposed adjacent theforgeand is branched out" from one side of thepipe section 2, saidintake having an enlarged mouth 8. A compressedair supply pipe 9 isconnected with the upper end of the section 2 above the rivet intakepipe and has a suitable valve .10 thereon. This air pipe is connectedwith a suitable source o-tcompressed air not shown, and has a nozzle 11extending into the pipe section 2, to a point substantially opposite thelower end of the intake pipe, so as to create a suction in the intakeJpipe. when the compressed air is directed downward into said section 2.

I [The vertical take-off section or pipe 4 is disposed at the pointwhere riveting of the plates 12 is required and this point may beforward. attor amidshi s the other i e 1 P a P P sections being suitablylaid to make proper connection with the pipe 1. Takeofl pipe is providedon-one side with a plurality of spaced hot rivet take-off or dischargeopenings 18, which may be three or more feet apart as desired. Each ofthe openings is controlled by independent means for open form.

ing and closing the same, which means is preferably the form of a sleeve14 rotatable upon the pipe and held against sliding thereon by,stopmeans 15,0f any suitable an opening as at 16 which is adaptedtoregister -W1tl1 an opening 13 when the sleeve is turned' or rotatedonthe pipe 1. When otherwise turned these sleeves will close thetake-oft or discharge openings. 1

3 To provide forjcatching, the rivets delivered through. the openings13, I employ a suitable bucket 17 having one side cut away. as at 18, soas to register with the openings 13 and 16. This bucket is supportedupon the pipe opposite the opening Each sleeve is slotted or formed withthe bucket I employ a deflecting member in the form of a tongue or strip20 carried by the bucket and arranged to extend through the openings 13and 16 into the pipe. 4 so as to lie in the path of the rivets. Thismember or tongue is inclined or shaped so that when the rivets come intocontact therewith they will be deflected sideways out through theopenings 13 and 16 in a clownward as well as outward direction and intothe bucket. The bucket is cut away on its outer sideas at 21, so. as topermit the operator to readily insert tongs, notshown, to remove therivets. Any suitable means may be usedfor temporarily holding the pipingin place and it is not thought necessary to describe this obviousexpedient.

O perat'ion.

A hot rivet is placed in the intakepipe 1 and the valve 10 isimmediately opened. A, charge of compressed air will be directed throughthe nozzle 11 into the piping 1 and willrapidly impel. the rivet throughthe piping. With the bucket set, as shown in Figs. 1 and 2, when therivet encounters the deflecting member 20, the rivet will be thrown ordischarged into the bucket from which it may be readily removed. Thevalve. need be kept open but a moment in order to cause the rivet to beforciblyand swiftly impelled and the rivet in thus being quicklydelivered in a metal pipe will not cool off and will be hot whendelivered tothe point of its use. Thus, each rivet requires but a smallan'iount of air to; cause its delivery through the piping. I v. 1

its the work advances the bucket is advanced along the pipe 4. If thepipe is 30 feet long, for example, and has from five to eight takeoffopenings, the bucket may be placedat any of these openings to receivethe rivets. this apparatus the rivets may be delivered Thus itwill beseen that with 7 hot at various pointsthroughout a height 24- with thetake-ofi' pipe 25 extending horizontally close to the bottom 26, of theship. This take-off pipe is connected with a system or line of piping 27which latter corresponds to the piping 1 of the form of inventionheretofore described, and said piping is connected with the air line andassociated with the forge, (both not shown) as in said piping 1. Theunder side of the take-off pipe 25 is providedwith a plurality of spaceddischarge or take-off openings 28 controlled by sleeves 29, rotatable onthe pipe and having openings 30 therein, adapted to register with theopenings 28. These sleeves are similar to the sleeves 14, beingindependently operable to open and close the openings 30.

A bucket 31 is movable along the pipes 25 so as to be disposed oppositeany of the openings 28 and has hooks 32 adapted to engage over and uponsaid pipe, whereby the bucket will hang under the said openings. Theoperator may slide the bucket from one opening 28 to another along thepipe, dependent on the point of work. To deflect the rivets a deflectingmember 33 is inserted into the pipe through the openings in the pipe andsleeves at the desired point along the pipe. This member is similar tothe one 19 and is carried on a curved jaw 34 of a two jaw clamp,the'other jaw 35 of which, being adjustably connected by means of bolts36 and nuts 37 The jaw 34 is curved to conform to and embrace the pipe,having lateral flanges 38 on its free ends. The jaw 35 engages upon theupper side of the pipe and the bolts 36 extend therethrough and throughthe flanges 38, with the nuts 39 on the upper ends thereof, whereby aquick clamping and unclamping may be effected. The operation of thisform of the invention is carried out in the same way as in the formhereinbefore described, the deflecting member and bucket being moved tothe desired point or advanced with the advancing of the rivetingoperation.

lVhile I have shown and described the invention in connection with'shipbuilding work, it is obvious it maybe equally well.
